Volcanoes Erupting All Over

Magmatic recharge detected beneath Laacher See volcano, Germany

For the first time since the improvement of the local seismic networks in the East Eifel region, Rhineland-Palatinate, Germany, scientists have detected and located recurrent deep low-frequency (DLF) earthquakes in the lower crust and upper mantle beneath the Laacher See Volcano (LSV), using a joint data set of permanent sensors and a temporary deployment. DLF microquakes suggest mass transport in the volcanic plumbing system and used to infer feeding channels from and into magma reservoirs.

So far, eight DLF earthquake sequences were observed in four distinct clusters at depths between 10 and 40 km (6.2 - 25 miles), scientists report in a study published recently in the Geophysical Journal International.

These clusters of weak events (ML< 2) align along an approximately 80° southeast dipping line south of the LSV. Moment tensor solutions of these events have large shear components, and the irregular dispersion and long coda of body waves indicate interaction processes between shear cracks and fluids.

"We find a rotation of P-axes orientation for shallow tectonic earthquakes compared to DLF events, indicating that the stress field in the depth interval of DLF events might favor a vertical migration of magma or magmatic fluids," authors say.

"The caldera of the LSV was formed by the last major eruption of the East Eifel Volcanic Field only 12.9 kyr ago, fed by a shallow magma chamber at 5 - 8 km (3.1 - 5 miles) depth and erupting a total magma volume of 6.7 km3 (1.6 mi3). The observed DLF earthquake activity and continuous volcanic gas emissions around the LSV indicate an active magmatic system, possibly connected with an upper mantle melt zone."


"We cannot say for sure that a large amount of magma is rising and we don't actually expect an immediate eruption very soon, or in the near future," said Dr. Torsten Dahm, Head of section 2.1: Physics of Earthquakes and Volcanoes at GFZ Potsdam and one of the authors of the new study, in an interview published in Deutsche Welle on February 6, 2019.

"It shows us that there is activity going on, and also magmatic activity. And it's the first time that we have direct evidence, meaning direct in the sense of observing seismic signals. So we know it's really occurring now," Dahm said.

"This is a destructive volcano," Dahm added. "13 000 years ago it erupted with such violence that its ash stopped the Rhine River. I still can't get over that. It makes me wonder, how are we monitoring Lake Laach right now, and what should we improve?"

Asked about CO2 gasses bubbling up in parts of the lake, Dahm said that there is a danger in this region. "And everywhere where you have CO2. As you know, CO2 can be dangerous. I always thought it was forbidden to swim in some areas of Lake Laach, or at least it was not recommended to swim there."

Geological summary
Activity at the East Eifel volcanic field began about 0.65 - 0.45 million years ago with the formation of scoria cones, lava flows and tephra deposits.

The Reiden volcanic complex at the western end produced a series of scoria cones, lava flows and lava domes from 0.45 to 0.35 Ma.

Activity resumed around 0.215 Ma, continuing until 0.115 Ma, with the formation of scoria cones, maars and lava flows.

The latest eruption, at the Laacher See maar, took place about 12 900 years ago (40Argon/39Argon age) and produced about 20 km3 of tephra (Schmincke et al., 2002). (GVP)

Eifel? as Eiffel as well?
 
Whoah! Popo is sure firing up there!
Yes, although it looks less impressive in color and real time (seated in front of the monitor :-))

February 15, 11:00 h (February 15, 17:00 GMT)

From 21:00 h yesterday began an episode of strombolian activity that consisted of harmonic tremor accompanied by explosions, which generated the emission of incandescent fragments which reached a distance of approximately 1.5 km on the flanks of the volcano, the height of the eruptive column was 2 km, which was dispersed preferably towards the southwest (vídeo 1) and (vídeo 2). The total duration of the episode was seven hours, after which the seismic activity returned to previous levels. Derived from this activity, at the time of this report has been detected ash fall in the communities of Hueyapan, Tetela del Volcán, Zacualpan, Temoac, Jantetelco, Cuautla, Ocuituco and Yecapixtla, belonging to the state of Morelos, as well as in Tochimilco, Puebla .

Additionally, 67 exhalations were recorded accompanied by steam and gases, in addition to five explosions, four recorded yesterday at 3:28 pm (image 1), 16:02 (image 2), 18:24 and 19:35 h, in all cases the eruptive column was less than 1 km high with low ash content, the last explosion was recorded at 04:09 h today (image 3). In addition, 10 minutes of low amplitude harmonic tremor were recorded. At the time of this report, continues a light emission of gases that are dispersed to the southwest direction (image 4).

CENAPRED (National Center for Disaster Prevention, acronym in Spanish) emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 5) and in case of heavy rains leave the bottoms of ravines by the danger of landslides and debris flows.

The Volcanic Traffic Light Yellow Phase 2.
The scenarios foreseen for this phase are:
  1. Explosive activity of low to intermediate level.
  2. Ash fall in nearby towns.
  3. Possibility of short range pyroclastic flows and mudflows .

Special emphasis is placed on the following recommendations:
  1. Continue the safety radius of 12 km, so staying in that area is not allowed.
  2. Keep the controlled traffic between Santiago Xalitzintla and San Pedro Nexapa through Paso de Cortés.
  3. Civil Protection authorities, keep your preventive procedures, in accordance with their operational plans.
  4. People, be alert to the official information disseminated.

In case of ashfall, address the following recommendations:
Cover nose and mouth with a handkerchief or face mask.
Clean eyes and throat with pure water.
Avoid contact lenses to reduce eye irritation.
Close windows or cover them up, and stay indoors as much as possible.

Popocatepetl Volcano monitoring is performed continuously 24 hours a day. Any change in activity will be reported in due course.

Update February 16, 20:20 h (February 17, 02:20 GMT)

From 16:00 h began an episode of harmonic tremor accompanied by the emission of water vapor and other gases that dispersed preferably in a northeasterly direction, the height of the column was at least 1.5 km (video 3). In the last hour, in addition to the constant emission of gases, incandescent fragments that fall on the flanks of the volcano at a short distance, approximately 400 m, have been observed. The height of the column has reached at least 2 km and is dispersed in a north-north-east direction. At this time incandescence is also observed that increases by some episodes, the tremor record persists (video 4).

This type of activity is contemplated within the Yellow Volcanic Alert Traffic Light Phase 2. Any change will be reported as soon as possible.

Strong eruption at Sheveluch volcano, Aviation Color Code Red, Russia
A strong explosive eruption took place at Sheveluch volcano, Kamchatka, Russia at 05:49 UTC on March 9, 2019. The Aviation Color Code was raised to Red.

The eruption ejected volcanic ash up to 10 km (33 000 feet) above sea level, drifting NW. This is 6.7 km (21 980 feet) above the crater rim.

Satellite data by KVERT showed the ash cloud at the height of 8 km (26 200 feet) a.s.l. continues to drift about 375 km (233 miles) to the north of the volcano, KVERT said 13:12 UTC.

A moderate gas-steam activity volcano continues at the volcano, the observatory said, adding that ash explosions up to 10 - 15 km (32 800 - 49 200 feet) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

KVERT reported that a thermal anomaly over Sheveluch’s lava dome was identified daily in satellite images during from February 22 to March 1. Strong gas-and-steam emissions contained variable amounts of ash on February 21, 25, and 27, and rose 4 - 5 km (13 100 - 16 400 feet) a.s.l. and drifted 100 km (62 miles) SW and E.

Sheveluch’s lava dome continued to grow, extruding blocks on the N side, and producing hot avalanches and fumarolic plumes during February and into March.

March 09, 11:00 h (March 09, 17:00 GMT)

In the last 24 hours, through the monitoring systems of the Popocatepetl volcano, 65 exhalations were identified, accompanied by a continuous emission of water vapor, gas and light amounts of ash (image 1). In addition, an explosion was recorded yesterday at 15:24 h that initially reached a height of 1500 m above the crater. Subsequently, as it was displaced by southwesterly winds, the emission reached approximately 3000 m (image 2). It was reported about the possible slight fall of ash in communities in that sector, such as Tochimilco, San Francisco Huilango and Huaquechula. Additionally, a volcanotonic earthquake was recorded at 23:13 h yesterday, with preliminary magnitude 1.8, 29 minutes of low amplitude tremor and 102 minutes of low amplitude exhalations between 4:25 and 6:07 hours today, lapse in which the exit of some incandescent fragments was observed (video 1).

Woah! Popo is really going at it lately! Years ago when I saw it, it only had an occasional wisp of smoke coming out.
As long as Iztaccihuatl doesn't wake up ... they may fight over her again, it wouldn't be convenient for us if that happen. :P

https://en.wikipedia.org/wiki/Popocat%C3%A9petl_and_Iztacc%C3%ADhuatl said:
"Popocatépetl and Iztaccíhuatl" refers to the volcanoes Popocatépetl ("the Smoking Mountain") and Iztaccíhuatl ("white woman" in Nahuatl, sometimes called the Mujer Dormida "sleeping woman" in Spanish)[1] which overlook the Valley of Mexico and the various myths explaining their existence. The most common variety relates the Nahua romance of the princess Iztaccíhuatl and the warrior Popocatépetl. This tale is recorded in several different versions.

A different tale was told by the Nahuatl-speakers of Tetelcingo, Morelos, according to whom Iztaccíhuatl (or Istācsohuātl, as they pronounce the name) was the wife of Popo, but Xinantécatl (Nevado de Toluca volcano ) wanted her, and he and Popocatépetl hurled rocks at each other in anger. This was the genesis of the rocky mountain ranges of the continental divide and the Trans-Mexican volcanic belt that lie between the two mountains. Finally Popocatépetl, in a burst of rage, flung an enormous chunk of ice, decapitating the Nevado de Toluca. This is why the Nevado is flat-topped, with wide shoulders but no head. Conceivably this legend preserves the memory of catastrophic eruptions. (Pittman 1954:59)
 
Powerful eruption at Bezymianny volcano, ash to 15.2 km (50 000 feet) a.s.l., Russia
A powerful eruption took place at Russian Bezymianny volcano at 17:29 UTC on March 15, 2019. The Aviation Color Code was raised to Red earlier in the day and lowered back to Orange at 21:20 UTC.

KVERT raised the Aviation Color Code to Red at 11:00 UTC today, stating that activity of the volcano continues to grow.

Amount of hot avalanches from the lava dome top considerably increased, ash plumes from avalanches extend for about 100 km (62 miles) to the SE of the volcano and the temperature of the thermal anomaly over the volcano began to grow, the observatory said at the time.

This activity culminated with a powerful eruption at 17:29 UTC, with volcanic ash ejected up to 15.2 km (50 000 feet) above sea level.
Ash cloud 79 x 65 km (49 x 40 miles) in size is drifting ENE of the volcano, KVERT said 18:53 UTC.

At 21:38 h an explosion was recorded that generated an emission of water vapour and gas with moderate ash content reaching a height of 1.2km in an easterly direction, and threw incandescent fragments 2.5km over the slopes. A slight drop of ash is expected in populations near the eastern sector of the volcano.

This activity is within the scenarios of the Yellow Volcanic Alert Traffic Light Phase 2. Any changes will be reported promptly.

That's new (bold part), in comparisson with latest reports, I guess there may be an increase of it's activity.
